Sea-Dog Stainless Steel Antenna Mount 1-14 Flange Base
Sea-Dog Stainless Steel Antenna Mount 1-14 Flange Base — Product description
The Sea-Dog stainless steel antenna mount gives you a solid, corrosion-resistant base for a VHF, GPS, or TV antenna. It uses the standard 1 inch-14 male thread and bolts down through a 2-7/8 inch round flange, so it sits flush on a deck, hardtop, or radar arch. Simple, strong, and built to shrug off salt spray for years.
If you've ever watched a cheap antenna mount rust out after a season, you already know why this Sea-Dog base is worth the money. It's machined from stainless steel, so salt spray, UV, and the constant pounding of open water don't chew it up the way plated pot metal does. This is the part you bolt down once and forget about.
The mount uses the standard 1 inch-14 male thread, which is the thread you'll find on the base of most marine VHF, GPS, Loran, and TV antennas. Thread your antenna on, snug it down, and you're set. The 2-7/8 inch round base gives you a wide, stable footprint, and the flange design means it bolts straight down through the deck or hardtop instead of hanging off the side. That flat, flush mount is exactly what you want on a hardtop, a radar arch, or a cabin roof where you need the antenna standing straight up.
Who's this for? Anybody rigging or re-rigging a fixed antenna. Center console owners mounting a VHF whip on the hardtop. Cruisers adding a GPS or TV antenna to the arch. It's a fixed base, so it holds the antenna rigid and vertical, no ratchet, no fold-down. If you need to lay the antenna flat to clear a low bridge or a garage door, this isn't the mount for that job, and you'd want a ratchet or fold-down base instead. But for a permanent, set-it-and-leave-it install, a rigid stainless base like this is the strongest, cleanest way to go.
Installation is straightforward. Pick a flat spot with clear sky above it and solid backing underneath. Mark and drill the flange holes, run a bead of marine sealant around the base to keep water out of the core, and bolt it down with stainless fasteners. Route your coax through and thread the antenna on. That's it. On most boats it's a 30-minute job.
One honest note. This is the mount only. Your antenna, coax, and mounting hardware aren't included, so check what you've already got before you order. If you're matching it to an existing antenna, confirm your antenna uses the common 1 inch-14 thread and you'll be good to go.

Frequently asked questions
What thread size does this Sea-Dog antenna mount use?
It uses the standard 1 inch-14 male thread, which is the common thread on most marine VHF, GPS, Loran, and TV antenna bases. Thread your antenna straight onto it.
What is the base diameter?
The round base measures 2-7/8 inches across, giving a wide, stable footprint for a rigid vertical mount.
Is this a fold-down or ratchet mount?
No. It's a fixed base, so it holds the antenna rigid and straight up. If you need to fold the antenna flat to clear a low bridge, you'd want a ratchet or fold-down base instead.
Is it really stainless steel?
Yes. It's machined from stainless steel, so it stands up to salt spray, UV, and years on the water without rusting out.
Does the antenna come with the mount?
No. This is the mount only. Your antenna, coax, and mounting hardware are sold separately, so check what you already have before ordering.
Where can I mount it?
Anywhere flat with clear sky above and solid backing underneath, such as a deck, hardtop, cabin roof, or radar arch. The flange bolts straight down for a flush, permanent install.
